Non Parametric Test

Nonparametric tests are statistical methods used to analyze data without making assumptions about the underlying data distribution, offering robustness when traditional parametric tests are unsuitable. Current research focuses on improving the efficiency and power of these tests, particularly in high-dimensional settings and for complex data structures like graphs, often employing kernel methods, machine learning models (e.g., for sequential testing), and techniques like bootstrapping or permutation testing to determine significance. These advancements are impacting diverse fields, enabling more reliable comparisons of algorithms, improved anomaly detection in spatial data (e.g., deforestation monitoring), and more powerful hypothesis testing in scenarios with limited data or unknown distributions.
